While a day does not go by without many public announcements of vulnerabilities in consumer and business software, it is rather rare when we hear about something wrong with software that is used to monitor or control industrial systems. Commonly called SCADA (Supervisory Control And Data Acquisition) or PCS (Process Control System), these are the systems that monitor and operate oil and gas refineries, large manufacturing plants, assembly lines, railroads, electrical grids, and countless other industrial processes.
Core Security announced yesterday that there is a Denial of Service vulnerability in the Invensys Wonderware InTouch SuiteLink service running in Windows operating systems, specifically
According to Wonderware's website, "Wonderware is the leading supplier of industrial automation and information software solutions. One third of the world’s plants run Wonderware software solutions. Having sold more than 500,000 software licenses in over 100,000 plants worldwide, Wonderware has customers in virtually every global industry — including Oil & Gas, Food & Beverage, Utilities, Pharmaceuticals, Electronics, Metals, Automotive and more." It's no wonder that a vulnerability in their monitoring software might be something the bad guys would be very interested in.
DHS (National vulnerability database) rates this one pretty high and says that the vulnerability "Provides unauthorized access, Allows partial confidentiality, integrity, and availability violation, Allows unauthorized disclosure of information, Allows disruption of service." Our advice: Patch now.
